Scientists Develop Membrane that Responds to Solvent Vapor

July 23, 2014

1 Comment

Material scientists have produced a membrane that curls very quickly when it comes into contact with the vapor from organic solvents, imitating biological structures which respond to an external stimulus like the Venus flytrap. An artificial skin now presented by a team working with scientists from the Max Planck Institute of Colloids and Interfaces in […]

First Experimental Evidence of Boron “Buckyball”

July 14, 2014

0 Comments

An international team of researchers has shown that boron, carbon’s neighbor on the periodic table, can form a cage-like molecule similar to the buckyball. Providence, Rhode Island (Brown University) — The discovery 30 years ago of soccer-ball-shaped carbon molecules called buckyballs helped to spur an explosion of nanotechnology research. Now, there appears to be a […]

Three-Atom Thick Crystal is Capable of Toggling Between Two Electrical States

July 2, 2014

0 Comments

New research from Stanford University shows how to make a three-atom thick crystal that would toggle like a light switch between conductive and non-conductive structures, opening the door to flexible electronic materials. Do not fold, spindle or mutilate. Those instructions were once printed on punch cards that fed data to mainframe computers. Today’s smart phones […]

MIT Develops Membrane That Can Separate Highly Mixed Oil-Spill Residues

July 1, 2014

0 Comments

A newly developed membrane can separate highly mixed fine oil-spill residues, processing large quantities of the finely mixed materials back into pure oil and water. Whenever there is a major spill of oil into water, the two tend to mix into a suspension of tiny droplets, called an emulsion, that is extremely hard to separate […]

Physicists Identify the Origin of Superconductivity in High-Temperature Superconductors

June 17, 2014

0 Comments

Researchers from the University of Cambridge have made a breakthrough in identifying the origin of superconductivity in high-temperature superconductors. They discovered that ripples of electrons, known as charge density waves or charge order, create twisted ‘pockets’ of electrons in these materials, from which superconductivity emerges. Harnessing the enormous technological potential of high-temperature superconductors – which […]

Physicists Observe Quantum Criticality in a New Class of Materials

June 5, 2014

0 Comments

Physicists have discovered new “quantum critical points” in a class of iron superconductors known as “oxypnictides,” furthering their understanding of quantum criticality. Quantum criticality, the strange electronic state that may be intimately related to high-temperature superconductivity, is notoriously difficult to study. But a new discovery of “quantum critical points” could allow physicists to develop a […]
